Lower Receiver

The lower receiver is the heart of the AR-15. It is the part that houses the trigger assembly, bolt carrier group, and magazine. It is also the part that is serialized, so it is the part that the government tracks.

There are a few different types of lower receivers available on the market. The most common type is the forged lower receiver. Forged lower receivers are made from a single piece of metal that is heated and then pounded into shape. This process creates a strong and durable lower receiver.

Another type of lower receiver is the billet lower receiver. Billet lower receivers are made from a block of metal that is CNC machined into shape. This process creates a lower receiver that is very precise and accurate.

The final type of lower receiver is the polymer lower receiver. Polymer lower receivers are made from a strong plastic material. They are lightweight and affordable, but they are not as strong as forged or billet lower receivers.

When choosing a lower receiver, you will need to decide what type of finish you want. The most common finishes are anodized black, hardcoat anodized black, and Cerakote. Anodized finishes are durable and corrosion-resistant, but they can be scratched. Hardcoat anodized finishes are even more durable than anodized finishes, but they are also more expensive. Cerakote finishes are a type of ceramic coating that is very durable and scratch-resistant.

You will also need to decide what type of fire control group you want. The fire control group is the part of the lower receiver that houses the trigger, hammer, and disconnector. The most common type of fire control group is the mil-spec fire control group. Mil-spec fire control groups are made to military specifications and are compatible with most AR-15 parts.

Another type of fire control group is the drop-in trigger assembly. Drop-in trigger assemblies are complete trigger assemblies that can be installed without having to remove the existing fire control group. Drop-in trigger assemblies typically offer a lighter trigger pull than mil-spec fire control groups.

Finally, you will need to decide what type of magazine you want. The most common type of magazine for AR-15s is the STANAG magazine. STANAG magazines are compatible with most AR-15s and hold 30 rounds of ammunition.

Upper Receiver

The upper receiver is the part of the AR-15 that houses the barrel, bolt carrier group, and gas system. It is also the part that is visible when the rifle is assembled.

There are a few different types of upper receivers available on the market. The most common type is the mil-spec upper receiver. Mil-spec upper receivers are made to military specifications and are compatible with most AR-15 parts.

Another type of upper receiver is the monolithic upper receiver. Monolithic upper receivers are made from a single piece of metal, which eliminates the need for a barrel nut. Monolithic upper receivers are typically more expensive than mil-spec upper receivers, but they are also stronger and more durable.

Finally, you will also need to choose a handguard for your upper receiver. Handguards are used to protect the barrel and provide a place to mount accessories such as lights, lasers, and sights. The most common type of handguard is the free-float handguard. Free-float handguards do not contact the barrel, which allows the barrel to free-float and improves accuracy.
